Inoculum (fermentation Starter)
A fermentation starter (called simply starter within the corresponding context, sometimes called a mother) is a preparation to assist the beginning of the fermentation process in preparation of various foods and alcoholic drinks. Food groups where they are used include breads, especially sourdough bread, and cheese. A starter culture is a microbiological culture which actually performs fermentation. These starters usually consist of a cultivation medium, such as grains, seeds, or nutrient liquids that have been well colonized by the microorganisms used for the fermentation. These starters are formed using a specific cultivation medium and a specific mix of fungal and bacterial strains.Norman F. Haard, S.A. Odunfa, Cherl-Ho Lee, R.

Mucor
''Mucor'' is a microbial genus of approximately 40 species of molds in the family Mucoraceae. Species are commonly found in soil, digestive systems, plant surfaces, some cheeses like Tomme de Savoie, rotten vegetable matter and iron oxide residue in the biosorption process. Description Colonies of this fungal genus are typically white to beige or grey and fast-growing. Colonies on culture medium may grow to several centimeters in height. Older colonies become grey to brown in color due to the development of spores. The species 'Mucor' belongs to the microbial kingdom: Fungi. ''Mucor'' spores or sporangiospores can be simple or branched and form apical, globular sporangia that are supported and elevated by a column-shaped columella. ''Mucor'' species can be differentiated from molds of the genera ''Absidia'', ''Rhizomucor'', and ''Rhizopus'' by the shape and insertion of the columella, and the lack of stolons and rhizoids. Some ''Mucor'' species produce chlamydospores. They fo ...

Sodium Carbonate
Sodium carbonate, , (also known as washing soda, soda ash and soda crystals) is the inorganic compound with the formula Na2CO3 and its various hydrates. All forms are white, odourless, water-soluble salts that yield moderately alkaline solutions in water. Historically, it was extracted from the ashes of plants growing in sodium-rich soils. Because the ashes of these sodium-rich plants were noticeably different from ashes of wood (once used to produce potash), sodium carbonate became known as "soda ash". It is produced in large quantities from sodium chloride and limestone by the Solvay process. Hydrates Sodium carbonate is obtained as three hydrates and as the anhydrous salt: * sodium carbonate decahydrate (natron), Na2CO3·10H2O, which readily efflorescence, effloresces to form the monohydrate. * sodium carbonate heptahydrate (not known in mineral form), Na2CO3·7H2O. * sodium carbonate monohydrate (thermonatrite), Na2CO3·H2O. Also known as crystal carbonate. * anhydrous sodium ...

Chinese Alcoholic Beverages
There is a long history of alcoholic drinks in China. They include rice and grape wine, beer, whisky and various liquors including ''baijiu'', the most-consumed distilled spirit in the world. Name (''jiǔ'') is the Chinese character referring to any drink containing appreciable quantities of ethanol. Its Old Chinese pronunciation has been reconstructed as ''*tsuʔ'',Baxter, William & al. "Baxter-Sagart Old Chinese reconstruction"p. 151. 20 February 2011. Accessed 5 November 2013. at which point it was generally applied to drinks made from fermented millet. By the time of the first certain use of distillation during the Jin and Southern Song dynasties, the Middle Chinese pronunciation was ''tsjuw''. It is often translated in English as "wine", which misrepresents its current usage. In present-day Mandarin, ''jiǔ'' most commonly refers to pure alcohol, hard liquors, and strong rice wine, while wine and beer are distinguished as ''pútáojiǔ'' (, lit. "grape ''jiu''") and ' ...

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Enzyme
Enzymes () are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts are catalytic RNA molecules, called ribozymes. Enzymes' specificity comes from their unique three-dimensional structures. Like all catalysts, enzymes increase the reaction ra ...

Microflora
Microbiota are the range of microorganisms that may be commensal, symbiotic, or pathogenic found in and on all multicellular organisms, including plants. Microbiota include bacteria, archaea, protists, fungi, and viruses, and have been found to be crucial for immunologic, hormonal, and metabolic homeostasis of their host. The term ''microbiome'' describes either the collective genomes of the microbes that reside in an ecological niche or within the microbes themselves. The microbiome and host emerged during evolution as a synergistic unit from epigenetics and genetic characteristics, sometimes collectively referred to as a holobiont. The presence of microbiota in human and other metazoan guts has been critical for understanding the co-evolution between metazoans and bacteria. Microbiota play key roles in the intestinal immune and metabolic responses via their fermentation product ( short-chain fatty acid), acetate. Introduction All plants and animals, from simple life fo ...

Acetobacter
''Acetobacter'' is a genus of acetic acid bacteria. Acetic acid bacteria are characterized by the ability to convert ethanol to acetic acid in the presence of oxygen. Of these, the genus ''Acetobacter'' is distinguished by the ability to oxidize lactate and acetate into carbon dioxide and water. Bacteria of the genus ''Acetobacter'' have been isolated from industrial vinegar fermentation processes and are frequently used as fermentation starter cultures. History of research The acetic fermentation was demonstrated by Louis Pasteur, who discovered the first acetobacter - ''Acetobacter aceti'' - in 1864. In 1998, two strains of ''Acetobacter'' isolated from red wine and cider vinegar were named '' Acetobacter oboediens'' and ''Acetobacter pomorum''. In 2000, ''Acetobacter oboediens'' and '' Acetobacter intermedius'' were transferred to ''Gluconacetobacter'' on the basis of 16S rRNA sequencing. In 2002, '' Acetobacter cerevisiae'' and '' Acetobacter malorum'' were identified b ...

Lactobacillus
''Lactobacillus'' is a genus of Gram-positive, aerotolerant anaerobes or microaerophilic, rod-shaped, non-spore-forming bacteria. Until 2020, the genus ''Lactobacillus'' comprised over 260 phylogenetically, ecologically, and metabolically diverse species; a taxonomic revision of the genus assigned lactobacilli to 25 genera (see below). ''Lactobacillus'' species constitute a significant component of the human and animal microbiota at a number of body sites, such as the digestive system, and the female genital system. In women of European ancestry, ''Lactobacillus'' species are normally a major part of the vaginal microbiota. ''Lactobacillus'' forms biofilms in the vaginal and gut microbiota, allowing them to persist during harsh environmental conditions and maintain ample populations. ''Lactobacillus'' exhibits a mutualistic relationship with the human body, as it protects the host against potential invasions by pathogens, and in turn, the host provides a source of nutrien ...

Hansenula Anomala
''Pichia'' (''Hansenula'' and ''Hyphopichia'' are obsolete synonyms) is a genus of yeasts in the family Pichiaceae with spherical, elliptical, or oblong acuminate cells. ''Pichia'' is a teleomorph, and forms hat-shaped, hemispherical, or round ascospores during sexual reproduction. The anamorphs of some ''Pichia'' species are '' Candida'' species. The asexual reproduction is by multilateral budding. The genus name of ''Pichia'' is in honour of Pico Pichi (1862-1933), who was an Italian botanist and Professor of natural history and plant pathology at a viticulture school in the town of Conegliano in the Province of Treviso. The genus was circumscribed by Emil Christian Hansen in Centralbl. Bakteriol., 2. Abt., 12 on pages 533-538 in 1904. Lactose is neither fermented nor assimilated by these species. The behaviour with regard to other carbohydrates is dependent on the different species. Nitrate is always assimilated. More than 100 species of this genus are known. GBIF lists 155. ...
